Extra (1995) is a short visual experiment - an amv of sorts - while fairly violent and set to interesting music, can be underwhelming.
Mind Game (2004) is the sped-up dialogue of Tatami's Galaxy but with the consistenty what said show sometimes lacks. It implies the way in which life is best lived and experienced in the moment, but doesn't build to this conclusion to the very last scene. Each scene prior explores the confusion and turmoil experiences before this realization, which fun action splices in to remind us this is another necessary aspect to life.
